SA-2/PSA~2X/PSA~2DX OUTPUT TRANSISTOR CHANGE
Because of availability problems with the C 4718-0 output transistor
used in the SA-2/PSA-2X/PSA-20X amplifiers. we are changing to a new
transistor. The new part number is C 5669-0.
The new output transistors were first used in the following serial
numbers
| MODEL SERIAL NUMBER
SA-2 12801
PSA~2X 11922
PSA-2DX 361
As of this date, we are using both types of output devices, however,
when servicing, keep in mind they are not interchangeable.
We have an alternate part (CPN C 5617-2) that is a direct replacement
for the 0 4718-0 with a small modification on the main module (when ordering
replacement output transistor C 4718-0, the C 5617-2 will be sent with
service letter #SA2PSA2 010881, explaining the modification procedures).
